  • A KINETIC MODEL OF ISOTOPIC EXCHANGE IN DISSOLUTION-PRECIPITATION PROCESSES 
    Dubinina E.O.; Lakshtanov L.Z. (1997)
    A model is derived for the isotopic fractionation between a mineral and a fluid phase in three dissolution-precipitation processes: the transformation of an unstable mineral into a stable one, and mineral-fluid mass transfer ...
  • CADMIUM ADSORPTION ON HEMATITE 
    Pivovarov S.A.; Lakshtanov L.Z. (2003)
    Cadmium sorption on the hematite-electrolyte solution interface was studied in a wide range of pH and Cd2+ concentration by means of potentiometric titration and measurement of cadmium content in the solution. Computer ...
  • ESTIMATES OF THE SECOND DISSOCIATION CONSTANT OF H2S FROM THE SURFACE SULFIDATION OF CRYSTALLINE SULFUR 
    Migdisov A.A.; Williams-Jones A.E.; Lakshtanov L.Z.; Alekhin Y.V. (2002)
    The adsorption of hydrogen sulfide (ΓH2S) and protons (ΓH+) on the surface of crystalline sulfur was investigated experimentally in H2S-bearing solutions at temperatures of 25, 50, and 70°C, NaCl concentrations of 0.1 and ...
  • EXPERIMENTAL STUDY OF EUROPIUM (III) COPRECIPITATION WITH CALCITE 
    Lakshtanov L.Z.; Stipp S.L.S. (2004)
    Partitioning of Eu(III) in calcite, CaCO3, was evaluated with the aim of collecting data on partition coefficients and to enhance understanding of the incorporation mechanisms. This information will aid in the interpretation ...
  • INFLUENCE OF TEMPERATURE ON STRONTIUM ADSORPTION ON HEMATITE 
    Karaseva O.N.; Ivanova L.I.; Lakshtanov L.Z. (2003)
    Adsorption on iron oxide surfaces controls, to a considerable extent, the mobility of trace elements in sediments and soils. The isotope 90Sr, which is produced in the nuclear reaction of uranium fission, is among the most ...
